MULTILAYERED GLASS, ITS MANUFACTURING METHOD AND ITS APPLICATION Russian patent published in 2021 - IPC C03C27/10 C03C17/06 B23K26/00 C03C17/23 

FIELD: glass production.

SUBSTANCE: inventions relate to the field of heating glasses, in particular aviation glasses. Multilayered glass contains from its first side, which should face the outside atmosphere, to its second side, a first sheet with a thickness of 0.5-12 mm, a first structural sheet with a thickness of 3-20 mm, possibly one or more other structural sheets with a thickness of 3-20 mm, and possibly a second sheet with a thickness of 0.5-12 mm, forming the second side of the glass, in which at least one side of the first or second sheet with a thickness of 0.5-12 mm, facing the structural sheet(s), and/or at least one side of the latter(s) contains an electrically conductive layer with a thickness of 2 to 1600 nm, except for at least one ablative line. The average slope of the edges of the ablative line does not exceed 5%.

EFFECT: provided is possibility to make the ablative lines invisible (or less noticeable in the case of very thick layers) in any observation conditions, increase the number of flow lines per area unit, improve the uniformity of heating, as well as reduce the electrical power required to combat icing/fogging of the glasses.
